Powdered styrene-butadiene rubber (PSBR) is widely used and Chinese enterprises have high R&D and production capabilities.

Styrene-butadiene rubber (SBR) is one of the most commonly used synthetic rubber varieties and is widely used in tires, hoses, tapes, wires and cables and other fields. Powder styrene-butadiene rubber, referred to as PSBR, refers to a styrene-butadiene rubber with a particle size less than 1mm and a white powder appearance. It is mainly polymerized from vinyl acrylate, butadiene, styrene and other monomers.

Powder styrene-butadiene rubber is a polymer elastomer material. It not only has the good friction resistance, grease resistance, aging resistance, and high temperature resistance of conventional styrene-butadiene rubber, but also has small particle size, good water resistance, good compatibility, and good bonding properties. With its advantages such as fast speed and strong chemical stability, it can be widely used in the production of tires, asphalt, medicine, coatings, rubber and other products. The terminal application fields include automobiles, chemicals, home appliances, machinery, medical care, construction, etc.

Among them, modified asphalt is the largest application field of powdered styrene-butadiene rubber. Powdered styrene-butadiene rubber is a material specially produced for modified asphalt. It has good compatibility with petroleum asphalt and can effectively improve the high and low temperature properties of asphalt. In recent years, against the background of the gradual upgrade of requirements for modern highways and roads such as flow resistance, low-temperature crack resistance, and abrasion resistance, the market penetration rate of modified asphalt has increased significantly, which in turn has driven the increasing demand and increasing production of powdered styrene-butadiene rubber.

According to the “China Powder Styrene Butadiene Rubber (PSBR) Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center shows that the domestic modified asphalt market size has reached 12.19 billion yuan in 2022, a year-on-year increase of 4.5%. As a result, domestic output of powdered styrene-butadiene rubber in 2022 will be around 180,000 tons. In addition, powdered styrene-butadiene rubber eliminates the need for rubber cutting and powder material mixing processes during processing, and has the advantages of low energy consumption and low environmental pollution. PSBR production faces less environmental pressure, and its output is expected to continue to increase in the future.

my country’s powdered styrene-butadiene rubber industry started in the early 21st century and achieved industrial production in 2005. The products meet the production requirements of modified asphalt for highways. Since then, through continuous research and development, a number of leading companies with R&D, scale and technical advantages have emerged in my country’s powdered styrene-butadiene rubber industry, such as Shandong Gaoshike Industry and Trade, Shandong Qiaolong Chemical Technology, Shandong Haifang Rubber Technology, Shandong Yuanguang Environmental Protection Technology, Shandong Xianyuan Chemical Technology, etc.

Industry analysts said that powdered styrene-butadiene rubber is a type of polymer elastomer material with excellent performance. It was first specially used for modified Chemical industrial products generated from asphalt have been developed in recent years and their advantages have become increasingly prominent. They also play an important role in the modification of resins, plastic products, and rubber products, and have a wide range of applications. my country’s powdered styrene-butadiene rubber industry is developing rapidly, and the number of companies in this field is increasing. Local companies already have strong independent research and development and large-scale mass production capabilities. In the future, domestic products are expected to continue to expand exports on the basis of satisfying the domestic market. The industry has huge potential for development.
